How can I create a function dictionary?

  • 772

I have a variable that I fill like this:

var animation = [String: Void]() 
animation["a"] = animationA()

But executing my code automatically executes the function animationA(), something I want to avoid, since what I want is that when I call the variable like this: animation["a"](), then it is executed.

And if I place the variable in the array as follows, animation["a"] = animationAit throws me an error.

Does anyone know if this can be done so that my function remains in a variable of an array?

Greetings and thanks in advance.

For an array I could do it, but not yet for a dictionary:

//Así lo declaro
var array: [(Void -> Void)] = [] 
//Aquí asigno la función
array.append { () -> () in
            self.animationDefault()
        }
//Así ejecuto la función
array[0]()

    After trying a thousand ways, I was able to do it like this:

    var animation: [String: () -> ()] = [
    "a":
    {() -> () in self.animationA()}
]
animation["a"]!()
